What fluid?

Could someone tell me what fluid I should be putting in the rear axle of my 3000?
I know its UTF, but in the UK I think its called UTTO, and the spec needs to be equivalent to MC134D.
Im new to classic tractors, and dont want to top up with the wrong fluid!
Any help would be gratefully received.

Your tractor required m-2c53A oil in the rear end,, manual shift transmission, and manual steering gear box housing. It required m-2c41A in the power steering and SOS transmission. There are many many universal tractor fluids that will met M-2C53A specifications, including much better fluids, M-2C134A, 134B, 134C, and 134D.


M-2C53A fluids were developed and approved for wet brakes, and pto clutches in the X000 series tractors.


The M-2C41A fluids could be substituted with Type F auto transmission fluids.

UTTO (Universal Tractor Transmission Oil), UTF (Universal Tractor Fluid), THF (Transmission Hydraulic Fluid), UTTHF (Universal Tractor Trans/Hydraulic Fluid), and some other names are used by different companies and people in referring to the same oil group. As sotxbill posted read the label and see that it meets the specs your tractor calls for.

No it doesn't. AB is fine for that tractor.....regular UTF, not Premium which is D....nothing in there requiring it.....tranny or live pto, external drum brakes,
manual steering or a separate, closed power assisted system, no hydrostatic this and that. Run it in your tranny too. Shifts easier in the
winter......drawbacks are it could drip easier than gear oil and the gears may make a little more noise....shifting can crunch a little more as the fluid doesn't
dampen as well. I like it better since the tranny isn't sychronized.....but it acts like it if you cut the throttle when down shifting.....fast up shifting never
notice it's not synchronized

Course I have a newer tractor of a different brand and it is a synchronized shuttle shift......when up shifting smooth as silk but down shifting you have to
wait to sync up simarily. On range with the new one, you have to be stopped...it has ABC range, 1234 speed per range and a creep for cutting the speed in
half on any gear for a total of 24 F and R.....Branson 6530. Obviously it uses Premium UTF.

The various letter suffixes for the M2C134 specification were chronological evolutions, where B superseded A, C superseded B, and D superseded C over time. Each newer one "meets or exceeds" the previous one. Most fluids on the market today will not even mention the A, B or C spec and only say that they meet or exceed the D spec, but I have seen a few that only mention the C spec and do not mention the D, and I assume that is based on the fluid maker not wanting to go through costly tests as often as some others.

There are many features that were added to oil specifications over the years. One of the features of the newer specs is the ability to handle water contamination better, and for older tractors that are not being used hard on a regular basis so that water is driven out by heat, I would rather have a newer spec oil than an older spec one even if the older spec meets or exceeds the original specification called for by the manufacturer.

A lot of the improvements found in newer specs didn't even exist when the tractor was designed and so the engineers who wrote up the fluid specs were basing those requirements on the oils that were available at the time. So if some of the newer features were available back then I am sure that the engineers would have included them in their requirements. So again, I would rather go with a fluid that meets or exceeds the latest spec that the original manufacturer says supersedes the original spec that was called for. Spending a few bucks more for a 5 gallon bucket of fluid is not a big deal to me when it could mean avoiding a costly repair down the road.

One of the problems folks (self included) have in reading manuals on older equipment is that things are specified in then current specifications. Hence
norman new guy wants to lube his this or that and pulls out the manual, it says xyz and they go looking for xyz, not the current fluid surpassing the original
specs.

I agree on using the best if it fits the need. Otherwise I don't. My new tractors get the best. The 50+ year olds with seldom useage don't. Figure I have
maybe 20 years left on the outside and kids have no aspirations attached to the place other than how much money they can milk out of me so........what!

Yes, but.... the newer specs were driven by higher pressures, much more heat, and newer power shift (automatic) transmissions that the 1965 -1975 tractors DID NOT HAVE. There is NO evidence of the factory spec fluids failing or causing a failure. We have over 50 years of testing that proves it.

AND... the utf fluids today....actually far exceed the original 1965 spec to various degrees but dont have the synthetic base oils. And the synthetic base oils are not needed in the these tractors or the engines as 50 years of proof shows. Same goes for the earlier type F or '43 spec. They gave proper service for the design life, and many automatic transmissions never got an oil change. Even the lowest spec hydraulic fluid used in loader applications was never changed till a hose burst and that oil did not fail under repeated loads, although the utf is a higher spec and a better fluid, approved for wet brakes and wet clutches.

Those in the sub arctic regions do benefit from the more expensive oils and fluids as even stated in the original manuals or can blend the lighter weight type f with the utf. Most of us dont plow below 20 degrees F. But a snow removal tractors/cars/equipment would benefit from synthetic blends.

Thanks for this guys, its frying my brains a little, but Im getting the gist. Modern fluid to spec will do the trick.

Modern fluids are generally backward compatible. If it has a spec # and ends in an A but the newer fluid ends in D it's the latest and greatest and will work in anything up to the latest equipment. Like GM transmission fluids that progressed from just Dexron to Dexron VI, it's backwards compatible.

The John Deere J20x specifications are/were the exception to that rule. J20A was the "normal temperature" version and J20B was the "cold" temperature version of their fluid that were both sold and spec'd during the same time period, and then C replaced A as the normal temp version and D replaced B as the cold temp version and then C & D were and still are both sold together, one for normal/hot weather and the other for cold weather.
